The potential is defined as follows: V(x)= 0 if x<-a Region I http://ursula.chem.yale.edu/~batista/classes/vvv/FiniteSquareWell.pdf

WebBut the potential in the problem is V(x, y) = V0Π(x / 2a)Π(y / 2a), where Π(x) is the rectangular function: Π(x) = 1 for − 1 / 2 ≤ x ≤ 1 / 2 and Π(x) = 0 otherwise. Equivalently we can express V in terms of Heaviside step functions, but either way, it never separates into a sum V(x) + V(y). – udrv Sep 9, 2015 at 3:37 1 http://hyperphysics.phy-astr.gsu.edu/hbase/quantum/pfbox.html

WebMay 23, 2024 · The finite potential well features a potential jump on its left. Generally, this jump will cause a strong reflection. However, at the energy of a resonance state, the external wave can efficiently transfer into one of the strongly confined states and subsequently has a high probability of going through to the other side.
